Spring-Loaded Thief Hatch

Model 330 Applications

ENARDO’s Model 330 is a spring-loaded pressure-vacuum relief hatch with a round base and cover. This hatch was specifically designed to meet the demand for a lightweight, inexpensive thief hatch and is generally used in applications where sealing requirements do not justify the use of a premium hatch.

For applications requiring the features of a premium hatch, specifically where tight sealing is critical such as sour crude/gas or where strict environmental standards are enforced, see ENARDO’s Model 660.
